Hello John, Is the lpg system fitted sequential injection or just a single point venturi mixer system? Lpg is harder to ignite than petrol & puts more load on the ignition system & therefore usually shows up any ignition weaknesses when running on lpg as oposed to petrol. I would have thought that it has a sequential injection system fitted & it could be that the petrol ecu is "learning away" because the fuel trims that it is trying to perform aren't having any effect. Usually if you clear the fault codes & then run on petrol & drive the car (if you can) it will re-adapt to run on petrol. I may be totally wrong but i have had this occur on a few different lpg converted vehicles. Hope this helps & doesn't send you on a wild goose chase, Regards Andrew
